, SEE RAD HARD HEXFET
International Rectifier’s SEE RAD HARD technology
HEXFETs demonstrate immunity to SEE failure. Ad-
ditionally, under
identical
pre- and post-irrradiation
test conditions, International Rectifier’s RAD HARD
HEXFETs retain
identical
electrical specifications up
to 1 x 10
5
Rads (Si) total dose. No compensation in
gate drive circuitry is required. These devices are also
capable of surviving transient ionization pulses as high
as 1 x 10
12
Rads (Si)/Sec, and return to normal op-
eration within a few microseconds. Since the SEE pro-
cess utilizes International Rectifier’s patented HEXFET
technology, the user can expect the highest quality
and reliability in the industry.
RAD HARD HEXFET transistors also feature all of
the well-established advantages of MOSFETs, such
as voltage control, very fast switching, ease of paral-
leling and temperature stability of the electrical pa-
rameters. They are well-suited for applications such
as switching power supplies, motor controls, invert-
ers, choppers, audio amplifiers and high-energy pulse
circuits in space and weapons environments.
